North of the city the land climbs a little toward Pennichuck Brook, and the calendar up there swings hard between green and white. Straight Up Service LLC takes both ends of it — mowing, trimming, edging and cleanups when the grass is running, plowing, shoveling and salting when it isn't. Same properties, same trucks, a different tool bolted on the front. Winter work is measured in driveways opened before daylight; summer work is measured in a clean edge along a walkway that still looks crisp on Friday. Nashua asks for both, and the answer is the same either way: show up and finish it.
